Box, especially for viscous substances



NW0 2%, 1933. A. BOENECKE BOX, ESPECIALLY FOR VISCOUS SUBSTANCES Filed May 2, 1935 Patented Nov. 28, 1933 BOX, ESPECIALLY FOR viscous SUBSTANCES Alfred Boenecke, Berlin, Germany Application May 2, 1933, Serial No. 668,968, and in Germany May 7, 1932 2 Claims.

Difierent kinds of boxes are known for viscous substances from which the contents are removed in certain determined quantities. For this purpose a pressure cover is arranged in the box, 5 which cover slides along a guide rod when a device outside the box is actuated, for example rotated.

To ensure a reliable up and down movement of the pressure cover in the box, it has been proposed to positively guide the pressure cover in grooves in the inner side of the box wall. In this instance it is therefore not possible to employ ordinary receptacles with a smooth inner wall surface. Moreover, special means for the reliable up and down movement of the pressure cover has also been dispensed with, when there is always a danger of the box not operating properly.

The arrangement according to the invention which ensures a perfect up and down movement of the pressure cover, consists of a simple guiding element which is hingedly mounted on the pressure cover and on a retaining disc of the box. It is therefore possible to employ smooth walled containers.

A further feature of the invention consists in that the guiding element in the form of a screwthreaded tube is rigidly connected to a rotary disc which rests loosely on the upper side of the retaining disc of the box.

An embodiment of the invention is illustrated by way of example in the accompanying drawing, in which:--

Fig. 1 shows the box in vertical section.

Fig. 2 is a top plan view of Fig. 1 partly in horizontal section. v

A receptacle or box 7 has a lid 9 which can be either screwed off the box or is connected thereto by a hinge. Besides the lid 9 a rotary disc 1 is provided on the top of the box, and this disc is rigidly connected to a screw threaded tube 3. Therefore, if the disc 1 is rotated, the tube 3 will also be rotated. A pressure cover 8 provided with a screw thread slides along the screw threaded tube 3. This pressure cover 8 is situated directly above the contents of the box. A retaining disc 2 is also provided which rests rigidly on the top of the box, being for example screwed thereon so that it cannot turn. The retaining disc 2 and the pressure cover 8 are hingedly connected at 5 by a guide element 4. A recess 10'is provided at the lower end of the screw threaded tube 3. The bore of the tube 3 is designated by 6.

As the screw-threaded tube 3 extends through the middle of the viscous substance, such as cream, it must be made of a material which does not have any detrimental effect on the contents of the box, for example the cream. The screw threaded tube 3 and also the pressure cover 8 coming into contact with the cream may be made of pressed material. The box '7 and the other component parts may likewise be made of pressed material.

The box operates in the following manner:-

In order to remove a certain quantity of cream from the box, the lid 9 is first removed, whereupon the disc 1 is rotated in one direction until the desired quantity of cream passes out of the tube bore 6. By turning the rotary disc 1 the screw threaded tube 3 is likewise rotated. Owing 7 to the fact that the pressure cover 8 is hingedly connected to the stationary returning disc 2 by the guide element 4, it can only turn to a limited extent and is compelled to move in downward direction. In this manner a downward pressure is exerted on the cream so that a certain quantity of cream enters the bore 6 and rises in the opposite direction to the pressure and thus passes out of the box.

To enable the contents of the box to enter the bore 6, the tube 3 does not bear tightly against the bottom of the box and also has a recess 10. The quantity of cream passing into the trough in the rotary disc 1 can then be used.

If too much cream is removed from the box, it can easily be returned therein by turning the rotary disc 1 in the opposite direction to that for the removal.

As the pressure cover 8 is hingedly connected to the retaining disc 2 by the guide element 4, the pressure cover 8 can move to the bottom of the box.

The refilling of the box is efi'ected by removing the rotary disc 1 together with the screw threaded tube 3, the pressure cover 8 and also the retaining disc 2.

I claim:-

1. A box especially for viscous substances, comprising in combination a receptacle, a retaining disc rigidly mounted on the top of said receptacle, a guide rod extending through the said retaining disc towards the bottom of said box, a pressure cover slidable on said guide rod, and a guide element hingedly connecting said retaining disc to said pressure cover and adapted to reliably guide said pressure cover up and down on saidguide rod.

2. A box especially for viscous substances, comprising in combination a receptacle, a retaining disc rigidly mounted on the top of said receptacle,

nected to the upper end of said tube, said rotary disc adapted to rotate said tube to cause said pressure cover to descend thereon and force the contents of said receptacle into and through said tube, from which it emerges at the upper end.
